Performance of Some Estimators of Relative Variability

open access: yesFrontiers in Applied Mathematics and Statistics, 2019
The classic coefficient of variation (CV) is the ratio of the standard deviation to the mean and can be used to compare normally distributed data with respect to their variability, this measure has been widely used in many fields. In the Social Sciences,

Statistical issues in simulation [PDF]

open access: yesProceedings of the 28th conference on Winter simulation - WSC '96, 1996
This paper describes, in general terms, methods to help design the runs for simulation models and in terpreting their output. Statistical methods are described for several different purposes, and related problems like comparison, variance reduction, sensitivity estimation, metamodeling, and optimization are mentioned.

Statistical Simulation of the Magnetorotational Dynamo

open access: yesPhysical Review Letters, 2015
Turbulence and dynamo induced by the magnetorotational instability (MRI) are analyzed using quasi-linear statistical simulation methods. It is found that homogenous turbulence is unstable to a large scale dynamo instability, which saturates to an inhomogenous equilibrium with a strong dependence on the magnetic Prandtl number (Pm).

On some beta ridge regression estimators : method, simulation and application

open access: yes, 2021
The classic statistical method for modelling the rates and proportions is the beta regression model (BRM). The standard maximum likelihood estimator (MLE) is used to estimate the coefficients of the BRM.

Washout filter control technique for a fractional-order chaotic finance model

open access: yesAin Shams Engineering Journal, 2022
On the basis of the previous publications, we set up a new fractional-order chaotic finance model. Taking advantage of washout filter controller, we are committed to the study on the chaotic control for the considered fractional-order chaotic finance ...

Causality inference of linearly correlated variables: The statistical simulation and regression method [PDF]

open access: yesComputational Ecology and Software, 2021
Causality inference of variables is a research focus in science. Due to its importance, a statistical simulation and regression method for causality inference of linearly correlated (scale or interval) variables was proposed in present study.

Simulation in statistics

open access: yesProceedings of the 2011 Winter Simulation Conference (WSC), 2011
Simulation has become a standard tool in statistics because it may be the only tool available for analysing some classes of probabilistic models. We review in this paper simulation tools that have been specifically derived to address statistical challenges and, in particular, recent advances in the areas of adaptive Markov chain Monte Carlo (MCMC ...
